Purpose: To determine compliance rates and characteristics and to investigate factors affecting patients' adherence to treatment with anti-vascular endothelial growth factors (anti-VEGFs) for diabetic macular edema (DME) in a cohort of Jordanian patients. Methods: A retrospective case series wherein the files of DME patients treated with anti-VEGFs were reviewed and analyzed for factors affecting treatment compliance was undertaken. Demographic, clinical and ocular characteristics were recorded. All patients were also interviewed by phone using a structured questionnaire. Univariate and multivariate analyses were performed to determine factors associated with compliance. Results: A total of 117 patients (65 males 52 females) were included in this study with a mean age of 62.93 years (±9.75). Approximately, 85% of patients were compliant to their treatment and follow-up plan during the first year of management. Subjective perception of visual improvement after receiving three loading doses was the only independent variable with a unique statistically significant contribution to compliance. All other studied factors in this group of patients were not significantly associated with patient compliance. Conclusion: VEGF suppression via the intravitreal route to treat DME is a long-term process that requires caregiver dedication but also proper patient compliance. Addressing real-life barriers in those patients may help guide future strategies to improve the treatment experience, lower the financial burden and contribute to better outcomes. Patients' perceptions of possible treatment outcomes at the short term may influence their long-term commitment to therapy.
Background: Silicone oil tamponade has become a mainstay in treatment of advanced retinal detachment due to multiple etiologies. The aim of this study is to assess the characteristics, fates and complications of long-term silicone oil tamponade after par plana vitrectomy (PPV), and to compare the outcomes of different silicone oil viscosities used in a cohort of consecutive patients. Methods: This is a retrospective comparative case series of eyes undergoing vitrectomy with silicone oil tamponade for retinal detachment by a single surgeon using different oil viscosities that were followed for one year with the silicone oil in situ. Visual acuity (VA), intraocular pressure (IOP) and complications associated with the follow up period were analyzed and compared. Results: Eighty-five eyes of 85 patients were included in this study. Forty three patients had 1000 centistoke (cs) oil injected and 42 patients had 5000cs oil utilized. Demographic, cause of retinal detachment and preoperative ocular characteristics were similar in both groups. Long term complications in both groups included ocular hypertension (67.4% vs 66.7%), keratopathy due to silicone oil emulsification and migration to the anterior chamber (7.0% vs 11.9%), recurrent retinal detachment (4.7% vs 19%) and epiretinal membrane formation (7% vs 19%). In the 1000cs oil group, there was no significant difference between baseline IOP and any subsequent visit. There was a significant difference between baseline IOP and visits at day 1 (with IOP difference of 2.61 mmHg (±6.5)) (p = 0.028), 1 month (with IOP difference of 3.52 mmHg (±8.1)) (p = 0.026), 4 months (with IOP difference of 6.38 mmHg (±9.3)) (p = 0.005), and one year (with IOP difference of 4.24 mmHg (±11.1)) (p = 0.048), all higher in the post-operative period in the 5000cs oil group. Excluding the first post-operative day, no significant difference was found for VA between baseline visits and subsequent visits for either silicone oil groups.
Background: The success of penetrating keratoplasty (PKP) is determined by the duration of graft survival, which is the time to graft failure. Our study aims to identify various indications of corneal graft among our Jordanian population, their success rate as well as spotting the light on cases of re-grafting. Methods: In this study, we analyzed data for patients who had PKP as well as re-do PKP in the period from January 2014 to June 2017. For each study eye, we identified pre-operative visual acuity as well as visual acuity at six months and one year. We also focused on the specific indication for PKP, the surgical procedure and graft clarity at one year post-op. On SPSS statistical analysis software, we used repeated measure ANOVA, Pearson correlations, and Fischer’s exact test to analyze our study’s variables.Results: We included a total of 230 patients in this study with a mean age of 34.22 (±19.32). They were 112 (48.7%) males and 118 (±51.3%) females. We found a significant difference in mean age and outcome (p< 0.001), as the mean age for patients with successful PKP was 31.55 (±16.55) compared to 44.1 (±25.1) for patients with failed PKP. the success rate for patients with KC as an indication was 96.7% compared to only 58.3% for other indications. We found that failure rate in redo surgeries was significantly higher than first time surgeries.Conclusion: Among the Jordanian population, we found that Keratoconus was the main indication for PKP in our population, where we also found that it was associated with the best prognosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
